WATER-TANK HEATER.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed July 11. 1907. Serial No- 383.199.

To all whom it may concem:

Be it known that I, DAVID H. QUINN, a citizen of the United States, residing at Williams, in the county of Beltrami, State of Minnesota, have invented certain new and useful Improvements in Water-Tank Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tank heaters, and has for its object to provide a simple construction of tank of this class which will effectually prevent freezing of the water contained therein.

A further object of the invention is to provide an integral construction of tank and heater, the heater being so placed in the tank that it may be readily fed with fuel and the ashes easily removed. r

In the accompanying drawings, Figure 1 is a front elevation of a tank heater constructed in accordance with my invention. Fig. 2 is a top plan view thereof, Fig. 3 is a vertical longitudinal sectional view through the tank and heater, and Fig. 4 is a vertical transverse sectional view through the same.

As shown in the drawings, the device comprises a tank including ends 5, a front 6, a bottom 7, and a back 8. In other words,the tank is of hollow rectangular construction as is usually the case.

The heater for the tank comprises a back 8, sides 9, a bottom 10, a top 11, and a front 12. The front 12 of the heater is disposed directly against the front wall of the tank proper and is preferably riveted thereto as indicated by the numeral 13.

Formed through the front of the heater is a fire box opening 14, and an ash pit opening 15 is also formed through the said front of the heater but below the fire box opening. Each of the openings has its edges flanged, as indicated by the numerals 16 and 17 respectively, and these flanges are extended throu h c u 0 b correspondmg openings in the front wall of A the tank, the latter openings being indicated by the numerals 18 and 19, respectively. After being passed through the openings in the front wall of the tank, the flanges 16 and 17 are bent back upon themselves and thence at right angles and outwardly, as at 20, and are riveted to the said front wall of the tank, thus firmly securing the heater in place within the tank.

Hinged, as at 21, to the flange at one side of the firebox opening is a door 22, and a similar door 23 is hinged, as at 24, to the corresponding side of the ash pit opening. The flanges above described not only constitute means for hinging the doors, but they also form desirable seats for the doors when the doors are closed.

The usual smoke flue leads upwardly from the top of the heater and is indicated bythe numeral 25, and within this flue is located a damper 26.

In order that the tank may overflow when it has become filled to a predetermined degree, I have provided in one end of the tank an opening 27, and this opening is located in a lower plane than the damper 26 in the smoke flue, so that the water within the tank can never reach such a level as to flow into the fine and extinguish the fire in the heater. Braces 28 serve to mutually brace the front and rear walls of the tank.

In the drawings, the heater is shown as being located about the middle of the front of the tank, but it will be understood that it may be otherwise located if found desirable.

What is claimed, is

A tank heater comprising a tank including a front wall, a heater located within the tank and comprising front and rear walls, sides, a bottom, and a top, the front wall of the heater being disposed directly against the front wall of the tank and being secured in this position, the front wall ofthe heater and the front wall of the tank being provided with registering firebox and ash-pit openings, the edges of the firebox and ash-pit openings in the front wall of the heater being flanged and the flanges being extended through the corresponding openings in the front wall of the tank and being bent back upon themwithin the flue and in a plane above that selves and thence outwardly at right angles occupied by the overflow opening. 10 and secured to the said. front wall of the tank, In testimony whereof, I a'HiX my signature firebox and ash-pit doors hinged to the in presence of two witnesses.
